I have so much trouble with congestion and mucus, I used afrin and I have never had any problem with rebound for several years. When my cold or allergy is gone, then I stop Afrin and no rebound. Well that is a different subject, if it causes rebound or not.
I tried everything to eliminate the congestion, nasonex, neti pot, allegra, etc. Nothing seemed to help. I also used Walgreens Nasal Spray (copy of Ocean from Flemming pharmaceuticals) and it didn't help. Every time I blew my nose I had blood on my mucus. I live in Houston, TX and work in Denver (for 15 days and then I fly back to Houston for the weekend). The dryness in Denver plus the CPAP therapy is causing the congestion.
I decided to try the real thing Ocean Saline spray, WoW, WoW. It has cleared my congestion, keeping my sinus moist. Blood has almost gone, I stopped Afrin cold turkey (I told you I have never had any rebound problem) and I breathe with my nose again. Hurray for Ocean!
Maybe your case is different but for me, it was the dryness in Denver compared to Houston that was causing my congestion.
Well back to the topic. I dread the Full Face Mask because I cannot have a good seal ( I am fat and my NEW DME, told me the problem is the extra meat in my cheeks cause the seal to break and the leak starts). The Ultra Mirage Full Face has been the worst mask I could ever tried. It didn't let me sleep with the flatulent noise and leaks, so I couldn't rest. I am trying the the Respironics ComfortGel Full, well the word comfort should be eliminated from the mask, but the leaks are 80% less than the Ultra Mirage. I just wake up a few times to re-accommodate the mask.
I can say that the Full Face mask does not help nasal congestion, the difference is that it does not exacerbate the problem, so Ocean Nasal Spray is doing its job plus the Full Face mask helps not causing more problems.
My problem is my nose is not ready for direct CPAP therapy provided by a nasal pillow, and I don't know if it will be any day.I don't know if a Hybrid can help my case because my nose problems.
